Characteristic analysis of thermal aging of tungsten delay composition

摘要：

　　Changes of delay time and thermal conductivity of tungsten delay composition with thermal aging time are discussed in this paper.Through a numerical regression, the relationship of the delay time and thermal conductivity can be used to achieve the fast calculation of the delay time during aging.The main conclusions are as follows:the delay time of tungsten delay composition changed, meanwhile, the thermal conductivity increased.To the tungsten delay composition which contains 30% tungsten, a quadratic equation can well coincide with the relationship of delay time and thermal conductivity during aging.
